Balanced Rain and Heat for Steady Growth

Reliable Soil Texture with Acidic Leanings

Exceptional Resilience to Recent Drought
Lawrence County only experienced 7 weeks in drought over the past year, far fewer than its neighbors. While 99.9% of the area is currently classified as abnormally dry, the historical lack of severe drought makes it a low-stress zone. Simple water-saving habits are usually enough to keep the turf green through the summer.
Maximize Success with the Right Timing
Hardiness Zone 6a favors Kentucky Bluegrass and Turf-Type Tall Fescue for a dense, green carpet. The last spring frost typically occurs on April 30, providing a safe start for spring projects, though fall remains best for seeding. With first frost not arriving until October 23, the autumn establishment window is quite generous.
